RESUMO
Xanthomas are localized lipid deposits within organs that may manifest as papules, plaques, or nodules in skin. They are commonly associated with all types of hyperlipidemia. Xanthoma striatum palmare characterized by xanthomas of the palmar creases is a rare but important diagnostic physical sign of dysbetalipoproteinemia, also known as type III hyperlipoproteinemia. Type III hyperlipoproteinemia is characterized by the early onset of cardiovascular disease and peripheral vascular disease. We describe herein the case of a 51-year-old female patient affected by xanthoma striatum palmare associated with elevated plasma levels of triglycerides and cholesterol and a lipoprotein electrophoresis pattern consistent with type III hyperlipoproteinemia.

We report a case of type IIa hyperlipoproteinemia associated with xanthoma planum and xanthoma striatum palmare. The laboratory findings showed increased serum cholesterol and triglyceride on the lipid profile, and an increased beta fraction on electrophoresis of lipoprotein, suggesting type IIa hyperlipoproteinemia. The biopsy specimens of orange yellow colored plaques on the left axillary area of a 54-year-old female showed characteristic findings of xanthoma.
